Want to get the most out of your air conditioner while keeping energy bills low? Whether you’re trying to beat the summer heat or maintain year-round comfort, there are simple steps you can take to make sure your AC is performing at its best.
Here are our top tips for optimising your air conditioning system—helping you stay cool, save money, and avoid unnecessary wear and tear.
✅ 1. Clean Your Filters Regularly
A dirty air filter restricts airflow and forces your system to work harder, using more energy and reducing cooling power.
How often? Every 1–3 months, depending on usage, pets, and allergies.
✅ 2. Keep the Outdoor Unit Clear
Check the outdoor condenser unit often and remove leaves, dirt, and obstructions. Make sure there’s at least 30cm of clear space around it for proper airflow.
✅ 3. Set the Right Temperature
Setting your thermostat too low won’t cool your space faster—it only wastes energy.
Ideal range for comfort and efficiency: 21°C–23°C during summer.
Bonus tip: Use a smart thermostat to create schedules or control the temperature when you’re not home.
✅ 4. Use Ceiling Fans to Circulate Cool Air
Ceiling fans or standalone fans help distribute cool air more evenly. This lets you raise your AC temperature by a couple of degrees while staying just as comfortable.
✅ 5. Keep Doors & Windows Closed
Make sure your windows and doors are shut while the AC is running. Warm air from outside will force the system to work harder and cool slower.
✅ 6. Block Out Direct Sunlight
Use blinds, curtains, or UV window film to reduce heat gain from sunlight—especially in south-facing rooms. Less heat = less work for your air conditioner.
✅ 7. Schedule Annual Servicing
Regular professional servicing keeps your AC system running smoothly, safely, and efficiently.
A full service includes:
- Cleaning internal components
- Checking refrigerant levels
- Testing performance
- Identifying issues before they become major faults
We recommend servicing at least once a year, ideally before the summer season kicks in.
✅ 8. Upgrade Old or Inefficient Units
If your air conditioner is more than 10 years old, it might be costing you more in running costs than it’s worth. Modern systems use far less energy and provide better performance.
